Problems solved by technology

The most commonly used zinc fertilizers are zinc sulfate heptahydrate, zinc sulfate monohydrate and zinc oxide, followed by zinc chloride, zinc-containing glass fertilizer, zinc lignosulfonate, zinc naphthenate emulsion and chelated zinc can all be used as zinc fertilizer ; In the traditional fertilizer granulation process, the fertilizer is stirred and mixed, and then a large amount of unformed fertilizer powder is mixed in the granulated fertilizer, so that the dissolution rate of the fertilizer is accelerated when the fertilizer is used, and it is harmful to the seeds. Or seedlings will cause damage, and it will also speed up the loss of nutrients; if these powder fertilizers or unformed fertilizers are manually screened, the manual labor intensity is high and the efficiency is low, and it is easy to reduce the production efficiency of fertilizers

Embodiment 1

[0043] like figure 1 , image 3 , Figure 5 , Image 6 , Figure 7 , Figure 8 As shown, the reduction motor 11 is connected to the processing box 7 by bolts, the stirring roller 12 is connected to the processing box 7 by bearings, the support base 14 is connected to the processing box 7 by welding, the turning plate 13 is connected to the processing box 7 by a shaft, and the gear motor 11 The rotating part drives the stirring roller 12 to rotate, and at the same time, the telescopic cylinder 15 is used to support the turning plate 13 when stirring the zinc fertilizer; the screening bucket 54 is connected to the support frame 6 by welding, and the recovery bucket 51 is connected to the support frame 6 by welding. Blowing blower 52 air suction port is connected with recovery bucket 51 by bolts, recovery air duct 53 is connected with processing box 7 by welding, recovery air duct 53 is connected with blower blower 52 air outlets by bolts, utilizes recovery bucket 51 to filte...

Embodiment 2

[0046] like figure 2 , Figure 4 As shown, the difference between Embodiment 2 and Embodiment 1 is that the granulation mechanism 2 includes a granulation motor 21, a granulation roller 22, and an auxiliary motor 213, and the front and rear ends of the granulation roller 22 are connected to the inner lower side of the processing box 7 through bearings. , the granulation motor 21 and the auxiliary motor 213 are all connected to the rear side of the processing box 7 by bolts and located below the rolling mechanism 4, the granulation motor 21 is located on the side of the auxiliary motor 213, and the granulation motor 21 is used to drive the granulator on one side. The granulation roller 22 is rotated, and the granulation roller 22 on the other side is driven by the rotating part of the auxiliary motor 213 to rotate, thereby realizing the opposite operation of the two granulation rollers 22.

Abstract

The invention discloses an extrusion granulation device for zinc fertilizer preparation. The device comprises a granulation mechanism for zinc fertilizer extrusion granulation, a conveying mechanism,a rolling mechanism, a support frame and a processing box; the processing box is mounted at the upper end of the support frame; the rolling mechanism is arranged in the middle of the interior of the processing box; the support frame is mounted at the lower end of the processing box; the granulation mechanism is arranged on the lower side of the interior of the processing box; the rolling mechanismis located above the granulation mechanism; and the conveying mechanism is arranged at the lower end of the inner side of the support frame. The granulation device further comprises a stirring mechanism and a recycling mechanism. A stirring roller in the processing box is driven by a gear motor to rotate; a powdery fertilizer is supported by an overturning plate, a supporting seat and a telescopic cylinder during stirring, so that the powdery zinc fertilizer raw material is stirred into a flocculent state; incomplete zinc fertilizer particles obtained after extrusion granulation are screenedand sucked away by the recycling mechanism, and therefore, the incomplete zinc fertilizer is put into a granulation box again to be granulated again.

Description

technical field [0001] The invention relates to the field of zinc fertilizer preparation, in particular to an extrusion granulation device used for zinc fertilizer preparation. Background technique [0002] Zinc fertilizer refers to a fertilizer with a marked amount of zinc to provide zinc nutrients for plants. The most commonly used zinc fertilizers are zinc sulfate heptahydrate, zinc sulfate monohydrate and zinc oxide, followed by zinc chloride, zinc-containing glass fertilizer, zinc lignosulfonate, zinc naphthenate emulsion and chelated zinc can all be used as zinc fertilizer ; In the traditional fertilizer granulation process, the fertilizer is stirred and mixed, and then a large amount of unformed fertilizer powder is mixed in the granulated fertilizer, so that the dissolution rate of the fertilizer is accelerated when the fertilizer is used, and it is harmful to the seeds. Or the seedlings will cause damage, and it will also speed up the loss of nutrients; if these po...
